Support the following...
1. Type checking and codegen support for V[i] on vectors. Hacked
Sema::ParseArraySubscriptExpr().
2. Unary bitwise complement ("~") on vectors. Hacked Sema::ParseUnaryOp().

typedef float float4 __attribute__((vector_size (16)));
void addFloat4(float4 a, float4 b) {
float4 temp;
}
make sure to add 'temp' to the stmt tree as a declstmt.

Typechecking support for vectors...
- Added CheckVectorOperands(). Called from CheckAdditionOperands,
CheckMultiplyDivideOperands, CheckSubstractionOperands, and CheckBitwiseOperands.
- Added diagnostic for converting vector values of different size.
- Modified Type::isArithmeticType to include vectors.
Sould be ready for Chris to add code generation. I will continue testing/refining.

Fix a bozo bug in HandleDeclAttribute...only install a new type when appropriate.
Also changed setType/setUnderlyingType to return void.

- Finished semantic analysis for vectors, added some diagnostics.
- Added AST for vectors (instantiation, installation into the decl).
- Fixed bug in ParseArraySubscriptExpr()...this crasher was introduced by me
when we added the range support.
- Turned pedantic off by default. Since vectors are gcc extensions, having
pedantic on by default was annoying. Turning it off by default is also
consistent with gcc (but this wasn't my primary motivation).
- Tweaked some comments and diagnostics.
Note: The type checking code is still under construction (for vectors). This
will be my next check-in.

- Fix for C++ casting operators failing during parsing. Deriving the C++ cast
expressions from CastExpr was the wrong way to go. Its constructor creates
null QualTypes in one of its constructors. This doesn't work well with how
the C++ casting expression class wanted to do things. Derive just from Expr
instead.

For example, for:
int test(short S, long L) {
return S /= L;
}
record that the division is done as a long, even though the result type is
short.

- Chris noticed that if there were multiple warnings/errors expected
throughout the file and we were checking only one of them, then it
would go ahead and say that the whole file was okay. Fixed this by
adding a check for the line number as well as the string.

- Added a new diagnostic client, TextDiagnosticBuffer. It buffers all
reported diagnostics.
- Use the new diagnostic client to check that expected diagnostics are
actually emitted. The way this is done is to put the expected
diagnostic in a comment on the line you expect it to be emitted for.
Like this:
int X = A; // expected-warning {{blah}}
- Use -parse-ast-check to use this feature.
